Frequently Asked Questions

How can a user cancel a subscription in my app?#

  • For both iOS and Android your users cannot cancel subscriptions inside your app. You need to direct your users to iTunes/the App Store or Google Play.

  • You can do this on iOS 12 or later (for earlier iOS versions, use this URL):

    Linking.openURL('https://apps.apple.com/account/subscriptions')

  • You can do this on Android:

    Linking.openURL('https://play.google.com/store/account/subscriptions?package=YOUR_PACKAGE_NAME&sku=YOUR_PRODUCT_ID

    (change YOUR_PACKAGE_NAME and YOUR_PRODUCT_ID)

Can I buy product right away skipping fetching products if I already know productId?#

  • You could only in Android in react-native-iap@^2.*.

    However, now you should always fetchProducts first in both platforms. It is because Android BillingClient has been updated billingFlowParams to include SkuDetails instead sku string which is hard to share between react-native and android.

    It happened since com.android.billingclient:billing:2.0.*.

    Therefore we've planned to store items to be fetched in Android before requesting purchase from react-native side, and you should always fetch list of items to “purchase” before requesting purchase.

How do I validate receipt in iOS?#

How do I validate receipt in Android?#

  • Offical doc is here.

  • I've developed this feature for other developers to contribute easily who are aware of these things. The doc says you can also get the accessToken via play console without any of your backend server.

    You can get this by following process:

    • Open Google Play Console> Select your app > Development tools > Services & APIs > Find in “Your license key for this application”. reference.

How to make consumable product in Android developer mode?#

  • If you are facing "You already own this item" on developer(test) mode, you might check related issue #126

How do I use react-native-iap in Expo?#

  • You should detach from expo and get expokit out of it.
  • Releated issue in #174.

How do I handle promoted products in iOS?#

  • Offical doc is here.
  • No initial setup needed from 4.4.5.

Somewhere early in your app's lifecycle, call initConnection first (see above), then add a listener for the iap-promoted-product event:

import { NativeModules, NativeEventEmitter } from 'react-native'
const { RNIapIos } = NativeModules;
const IAPEmitter = new NativeEventEmitter(RNIapIos);
IAPEmitter.addListener('iap-promoted-product', async () => {
// Check if there's a persisted promoted product
const productId = await RNIap.getPromotedProductIOS();
if (productId !== null) { // You may want to validate the product ID against your own SKUs
try {
await RNIap.buyPromotedProductIOS(); // This will trigger the App Store purchase process
} catch(error) {
console.warn(error);
}
}
});

Using Face ID & Touch to checkout on iOS#

  • After you have completed the setup and set your deployment target to iOS 12, FaceID and Touch to purchase will be activated by default in production.

    Please note that in development or TestFlight, it will NOT use FaceID/Touch to checkout because they are using the Sandbox environment.
